A methanol steam reformer converts methanol and steam into a hydrogen-rich mixture through an endothermic reaction. The methanol reformer is divided into a reaction section and a heat supply section that transfers thermal energy from 200 to 300 °C. This study presents the behavior of the methanol steam reforming reaction using the latent heat of the steam. A numerical analysis was separately conducted for two different regimes assuming constant heat flux conditions. A methanol steam reformer is an annulus structure that has a phase change heat transfer from an outer tube to an inner tube. Different from the steam zone temperature in the tube, the latent heat of steam condensation decreases, and there is a gradual between-wall temperature decrease along the longitudinal direction. Since the latent heat of steam condensation is very sensitive to the requested heat from the reformer, it is necessary to consider a refined design of a methanol reformer to obtain a large enough amount of heat by steam condensation.

“…In 2001, the European Union launched the CUTE (Clean Urban Transport for Europe) demonstration project, which involved operating 27 hydrogen fuel cell‐powered busses in nine major metropolitan areas (Amsterdam, Barcelona, Hamburg, London, Luxembourg, Madrid, Porto, Stockholm, and Stuttgart) over a 2‐year period . In the UK, a Hydrogen and Renewables Integration (HARI) project was initiated in 2001 to convert the energy produced by various renewable energy sources (eg, solar panels, wind turbines, and microhydropower) into hydrogen by means of an electrolysis process . As fuel cell technology continues to advance, hydrogen is expected to become the main source of renewable power for transportation applications.…”

However, irrespective of the scale and nature (stationary or mobile) of the hydrogen power generation system, further work is required to improve the overall efficiency of the hydrogen reforming and storage processes.…”

Summary MATLAB/Simulink simulations are performed to investigate the hydrogen molar fraction of the reformate gas produced by four methanol‐water fuel mixtures with molar ratios of 50%:50%, 62%:38%, 75%:25%, and 100%:0%, respectively. The simulations utilize the Thermolib module and investigate the hydrogen reforming performance of the four fuels for fuel flow rates in the range of 0.1 to 1 mol · min−1 and reaction temperatures ranging from 500 to 1000 K. The results show that the hydrogen molar fraction of the reformate gas decreases with an increasing methanol content. By contrast, for a given methanol concentration, the hydrogen molar fraction generally increases with an increasing flow rate and reaction temperature. Overall, the results show that the maximum hydrogen molar fraction (73.10%) is obtained using the 50%MeOH:50% water fuel mixture with a flow rate of 0.5 mol · min−1 and a reaction temperature of 800 K.
